Fuse connection terminal

Abstract

To obtain a fuse connection terminal with high durability.SOLUTION: A leaf spring 12A is formed to have such a shape that, when extending from a negative side to a positive side in an x direction, the leaf spring separates again from a central axis X after bending so as to protrude toward the central axis, and is further bent toward a negative side in the x direction from a positive side in a y direction at a tip portion. Thus, the tip portion of the leaf spring 12A (12B) serves as an outer support part 12A1 (12B1) extending from the positive side to the negative side in the x direction while closing to a side 13A (13B). When a tab terminal is inserted from an end face opening 11A toward the negative side in the x direction, the tab terminal comes into contact with tab terminal contact portions 12A2, 12B2. Deformation modes of the leaf springs 12A, 12B are limited by the contact of the outer support parts 12A1, 12B1 with the sides 13A, 13B, respectively.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to a fuse connection terminal to which a fuse or the like is attached. [Background technology]

[0002] In automobiles and the like, connection terminals are used to mechanically fix and electrically connect electrical components (including wiring). One form of connection terminal is a connector that connects ordinary wiring together. Generally, harnesses in which many wires are bundled together are used, and in order to connect the harnesses together, multi-pole connectors in which many terminals are arranged so that each wire can be connected simultaneously are widely used.

[0003] On the other hand, components such as fuses, which are expected to be replaced when necessary, such as when they blow or during regular inspections, are also attached to connection terminals. Fuses usually have only two terminals, and because large currents flow through these terminals, their structure differs significantly from that of the general wiring connectors described above. While the terminals used in the wiring connectors described above are small and have a small contact area that allows for arrangement, the fuse terminals used for these connectors are large, flat terminals (tab terminals) that can handle large currents, and the fuse connection terminals to which these are attached also have a corresponding structure.

[0004] In the wiring connector described above, a connector provided with a terminal to which one of the wirings (harnesses) to be connected is fixed is connected to a connector provided with a terminal to which the other wiring (harness) is fixed, and a large number of terminals corresponding to the respective wirings are connected simultaneously. In this case, the terminals are arranged in a large number in a plane perpendicular to the direction of movement when the connectors are connected, so that a large number of terminals can be connected simultaneously. In this structure, the terminals on one connector are not connected in an inclined state relative to the terminals on the other connector.

[0005] In contrast, in the above-mentioned fuse connection terminal, the tab terminal on the fuse side may be installed in an inclined state. For this reason, the fuse connection terminal is designed to reliably connect the terminals together and allow a large current to flow between them, taking such a situation into consideration. Such a structure is described, for example, in Patent Documents 1 and 2. In this fuse connection terminal, two large leaf springs are used to secure the tab terminal from both sides. While the above-mentioned wiring connector requires each terminal to be small, fuse connection terminals are larger than this, so a structure in which the tab terminal is secured from both sides with such large leaf springs is effective.

[0006] Such a leaf spring is not a separate component from the fuse connection terminal, but can be formed as part of the fuse connection terminal when a single metal plate is processed to form the fuse connection terminal, which allows the fuse connection terminal to be manufactured inexpensively and also increases the fixing strength of the leaf spring in the fuse connection terminal.

[0008] Although a fuse connection terminal that secures a tab terminal with two leaf springs can secure an inserted tab terminal even in an inclined position, when the tab terminal is inserted in this inclined position, a large load is applied unevenly to one of the leaf springs, especially at the base of the leaf spring when it is formed. This causes significant deformation of the leaf spring, which can lead to plastic deformation and deterioration. This reduces the durability of this fuse connection terminal, and a fuse connection terminal with higher durability is desired.

[0009] The present invention has been made in view of the above circumstances, and has as its object to solve the above problems. [Means for solving the problem]

[0010] The present invention provides a fuse connection terminal that clamps and fixes a plate-shaped tab terminal connected to a fuse from both sides, and includes a terminal portion that fixes the tab terminal inserted from one side to the other in a first direction along the surface of the tab terminal, and the terminal portion includes, on one side and the other side in a second direction perpendicular to the surface of the inserted tab terminal as viewed from a central axis along the first direction, leaf springs formed continuously from metal plates from a side surface on one side and a side surface on the other side of the terminal portion so as to abut against the tab terminal from the one side and the other side, respectively, and the leaf springs are formed by pinching the side surface on the corresponding side in the first direction. the leaf spring is bent to form a tab terminal abutment portion that is taken out from the side surface toward the central axis at an take-out portion provided on the other side in the first direction and extends to the one side in the first direction, a tab terminal abutment portion that protrudes toward the central axis on the one side in the first direction beyond the take-out portion, and an outer support portion that is folded back on the one side in the first direction beyond the tab terminal abutment portion from the one side toward a side away from the central axis and the other side in the first direction, to face the side surface on which the leaf spring is present, and the tab terminal is configured to be sandwiched between the tab terminal abutment portions of the leaf springs on both sides. The flat spring may include a flat spring tip bent portion configured by bending a tip thereof toward the central axis on the other side in the first direction relative to the outer support portion. The extraction portion may be provided on one side in a third direction perpendicular to the first direction and the second direction, and may include a leaf spring movement limiting portion that is extracted from the side surface on which the leaf spring is located toward the central axis from the other side in the third direction toward the central axis and extends along the third direction, closer to the central axis than the leaf spring. The side surface on which the leaf spring is located may be provided with a protrusion that locally protrudes from the side surface toward the leaf spring on the other side in the third direction. [Effects of the Invention]

[0011] Since the present invention is configured as described above, it is possible to obtain a fuse connection terminal with high durability. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] A fuse connection terminal according to an embodiment of the present invention will be described. A large, plate-shaped terminal (tab terminal) is attached to this fuse connection terminal. This tab terminal is fixed by being clamped from both sides by leaf springs, similar to the techniques described in Patent Documents 1 and 2.

[0014] (First embodiment) 1A and 1B are views of a fuse connection terminal 1 according to a first embodiment as viewed from two different directions. Here, the direction in which a tab terminal attached to the fuse connection terminal 1 is detached is the same as the extension direction of the wiring fixed to the fuse connection terminal 1, and this direction is referred to as the x-direction (first direction). The tab terminal is attached to the fuse connection terminal 1 by moving it from the positive side (one side) to the negative side (the other side) in the x-direction. The attached tab terminal is planar with the y-direction (second direction) as its normal direction, and the z-direction (vertical direction: third direction) is perpendicular to the x- and y-directions.

[0015] 1, the fuse connection terminal 1 is formed by processing a metal plate and is configured by integrating a terminal portion 10 provided on the positive side of the x direction and having a substantially rectangular outer shape with its sides parallel to the x-axis, y-axis, and z-axis and long in the x direction, with a wiring fixing portion 40 provided on the negative side of the x direction and to which a wiring is fixed. The wiring fixed to the wiring fixing portion 40 and a tab terminal (fuse) attached to the terminal portion 10 are electrically connected.

[0016] This wiring is configured such that a core wire (conductor) is covered with an insulating covering layer along its extension direction, and the covering layer near the tip of the core wire is removed to expose the core wire. This exposed core wire is fixed by bending (crimping) a plate-shaped first wiring fixing portion 41 provided on the positive side of the x-direction in wiring fixing portion 40, and the covering layer adjacent to this portion is fixed by bending a second wiring fixing portion 42 provided on the negative side of the first wiring fixing portion 41 in the x-direction. This mechanically and electrically fixes the wiring to wiring fixing portion 40 (fuse connection terminal 1).

[0017] An end surface opening 11A, through which a terminal tab is inserted, is formed in the end surface (terminal portion end surface 11) on the positive side in the x direction of the terminal portion 10. The end surface opening 11A corresponds to the shape of the terminal tab and is formed narrow in the y direction and long in the z direction.

[0018] Leaf springs (fixing leaf springs) 12A and 12B are provided symmetrically on the positive and negative sides of the end-face opening 11A in the y direction inside the terminal portion 10. As shown in FIG. 1(a), the fixing leaf springs 12A and 12B are formed by extending and bending metal plates constituting the side surface 13A on the positive side in the y direction and the side surface 13B on the negative side in the y direction, respectively, of the terminal portion 10 from extraction portions 13A1 and 13B1, which are on the positive side (one side) in the z direction and the negative side in the x direction of the side surface 13A and the side surface 13B. Therefore, the leaf springs 12A and 12B are actually configured integrally with the terminal portion 10.

[0019] The leaf spring 12A extends from the position where it is taken out from the take-out portion 13A1 on the negative side of the y direction toward the positive side of the x direction, and is bent so that its tip points toward the positive side of the y direction (the side where the side surface 13A is located) and then toward the negative side of the x direction. The shape of the leaf spring 12B is symmetrical to the leaf spring 12A in the y direction. As shown in FIG. 1(a), the leaf springs 12A and 12B are formed to extend over the entire area of ​​the terminal portion 10 in the z direction. Therefore, when a plate-shaped tab terminal that extends from the positive side of the x direction in both the x and z directions is inserted, the tab terminal can be sandwiched between the leaf springs 12A and 12B.

[0020] As shown in FIG. 1(a), an opening (bottom opening 14A) is provided on the bottom surface 14 of the terminal portion 10 on the negative side in the z direction, and a leaf spring movement limiting portion 15A is provided which is bent to extend from the edge of this opening along the x direction toward the positive side in the z direction, and a leaf spring movement limiting portion 15B is provided which is symmetrical to the leaf spring movement limiting portion 15A in the y direction.

[0021] 2(a) is a cross-sectional view of the terminal portion 10 taken perpendicular to the z-direction, and FIG. 2(b) is a cross-sectional view of the terminal portion 10 taken along the AA direction (perpendicular to the x-direction). Also shown in FIG. 2(a) is a central axis X passing through the center of the terminal portion 10 in the y-direction. The illustration mainly shows the leaf springs 12A and 12B and their surrounding structures.

[0022] As shown in FIG. 2(a), when the leaf spring 12A extends from the negative side to the positive side in the x-direction, it bends toward the central axis X, then moves away from the central axis X again, and then its tip is bent from the positive side to the negative side in the y-direction. Therefore, the tip of the leaf spring 12A (12B) in FIG. 2(a) forms an outer support portion 12A1 (12B1) that extends from the positive side to the negative side in the x-direction close to the side surface 13A (13B). Furthermore, when no force is applied to the leaf springs 12A and 12B, the distance between the portions of the leaf springs 12A and 12B that protrude toward the central axis X (tab terminal contact portions 12A2 and 12B2) is smaller than the thickness of the tab terminal to be attached along the y-direction. Therefore, when a tab terminal is inserted through the end surface opening 11A toward the negative side in the x-direction, the tab terminal contacts the tab terminal contact portions 12A2 and 12B2. Furthermore, the leaf spring 12A is integrated with the side surface 13 at its base portion on the negative side in the x direction and the positive side in the z direction, but is separated from the side surface 13A apart from the base portion, as shown in Figures 2(a) and (b).

[0023] As shown in FIG. 2(b), a protrusion 13A2, which is a small protrusion that protrudes inward (toward the negative y-direction), is formed on the lower side of the inner surface of the side surface 13A. On the bottom surface, a leaf spring movement limiter 15A extending from the bottom surface 14 along the z-direction toward the positive z-direction is formed on the negative y-direction side of the leaf spring 12A. Therefore, as shown in FIGS. 2(a) and 2(b), the leaf spring 12A is sandwiched between the protrusion 13A1 and the leaf spring movement limiter 15A. The leaf spring 12B has a structure symmetrical to the leaf spring 12A in the y-direction and is similarly provided with a leaf spring outer support portion 12B1. Similarly, a protrusion 13B2 and a leaf spring movement limiter 15B are also provided on the side surface 13B, and the leaf spring 12B is similarly sandwiched between them.

[0024] 3(a) to 3(c) show the state when the tab terminal 200 is inserted into the terminal portion 10 having this structure in a cross section similar to that of Fig. 2(a). In these figures, the main surface of the tab terminal 200 is perpendicular to the paper surface (the normal line is the up-down direction in the figure).

[0025] First, as shown in Fig. 3(a), when the tab terminal 200 is inserted from the end surface opening 11A toward the negative side in the x direction, the tab terminal 200 comes into contact with the tab terminal contact portions 12A2, 12B2. As shown here, the tab terminal contact portions 12A2, 12B2 are shaped so that the distance therebetween increases toward the positive side in the x direction. Therefore, as shown in Fig. 3(b), the operator can further push the tab terminal 200 from this state toward the negative side in the x direction.

[0026] 3(b), a force is applied to tab terminal contact portions 12A2 and 12B2 in the positive and negative y-directions, respectively, and they deform in response to this force. This force causes leaf springs 12A and 12B to deform so that outer support portions 12A1 and 12B1 move toward side surfaces 13A and 13B, respectively, in region B. At this time, outer support portions 12A1 and 12B1 abut against side surfaces 13A and 13B, respectively, and further outward movement is restricted.

[0027] In this way, the deformation of the leaf springs 12A and 12B is limited by the outer support portions 12A1 and 12B1 abutting against the side surfaces 13A and 13B, respectively, so that the leaf springs 12A and 12B do not tilt more than in the state shown in Figure 3(b). In this state, the leaf springs 12A and 12B are compressed in the y direction like the leaf springs 12A and 12B in the state shown in Figure 2(a).

[0028] 3(c), in this state, the tab terminal 200 can be further pressed toward the negative x-direction. In this state, the tab terminal 200 is firmly fixed by the elastic forces of the leaf springs 12A and 12B that accompany the compression.

[0029] FIG. 4 shows the state corresponding to FIG. 3(b) when the tab terminal 200 is inserted at an angle. In this case, the tab terminal 200 does not abut against the leaf spring 12B (tab terminal abutment portion 12B2), so the state of the leaf spring 12B remains the same as in FIG. 2(a). On the other hand, in region C, the tab terminal 200 abuts against the leaf spring 12A (tab terminal abutment portion 12A2), so the leaf spring 12A is compressed, as in the case of FIG. 3(b). However, the degree of this compression is limited by the abutment of the outer support portion 12A1 with the side surface 13A in region A, so the shape of the leaf spring 12A at this time is not significantly different from that shown in FIG. 3(b). Alternatively, a large force would be required to compress the leaf spring 12A further, making it practically difficult to insert the tab terminal 200 at a large angle.

[0030] In the technologies described in Patent Documents 1 and 2, when a tab terminal is inserted in an inclined state, a load is applied to only one of the leaf springs, as described above. However, in this case, the leaf spring is deformed in an inclined manner by the load, making the base portion more susceptible to plastic deformation.

[0031] In contrast, in the above-described structure, even if this load is applied to only one of the leaf springs (leaf spring 12A), outer support portion 12A1 abuts side surface 13A, preventing leaf spring 12A from tilting significantly. Instead, leaf spring 12A is compressed in the y direction as a whole, preventing specific portions, such as the base portion, from undergoing particularly large plastic deformation. This improves the durability of terminal 10.

[0032] 2(b), if the lower side (negative side in the z-direction) of the leaf spring 12A (12B) were in close contact with the side surface 13A (13B), the leaf spring 12A (12B) would be prone to tilting around this part as a fulcrum. For this reason, the protrusion 13A2 (13B2) in FIG. 2(b) prevents the leaf spring 12A (12B) from coming into close contact with the side surface 13A (13B) on the lower side. That is, the protrusion 13A2 (13B2) restricts the movement of the leaf spring 12A (12B) toward the positive (negative) side in the y-direction on the lower side.

[0033] 2(b), a leaf spring movement limiting portion 15A (15B) is provided on the side of the leaf spring 12A (12B) opposite to the side where the protrusion 13A1 (13B1) is located, so that movement of the leaf spring 12A (12B) to the negative (positive) side in the y direction is limited by the leaf spring movement limiting portion 15A (15B).

[0034] As described above, the protrusion 13A2 (13B2) and the leaf spring movement limiter 15A (15B) limit the displacement of the leaf spring 12A (12B) in the y direction on the lower side in FIG. 2(b). However, while the protrusion 13A2 (13B2) and the leaf spring movement limiter 15A (15B) limit large displacements, small displacements are possible. Therefore, this structure also prevents the leaf spring 12A (12B) from tilting significantly and prevents plastic deformation of the base of the leaf spring.

[0035] That is, by using the leaf spring 12A (12B) having the outer support portion 12A1 (12B1) and the tab terminal abutment portion 12A2 (12B2) and made of the same metal plate as the side surface 13A (13B) as described above, and further using the protrusion portion 13A2 (13B2) and the leaf spring movement limiting portion 15A (15B) that limit large displacement at the base portion, the durability of this fuse connection terminal 1 can be improved, particularly when the tab terminal 200 is inserted at an angle.

[0036] However, in the above configuration, as described above, the contact between the outer support portion 12A1 (12B1) and the side surface 13A (13B) suppresses deformation of the leaf spring 12A (12B) that would otherwise tilt significantly. Therefore, if sufficient durability can be obtained by this alone, in order to simplify the structure of the terminal portion, a configuration may be adopted in which only either the protrusion or the leaf spring movement limiter is provided, or neither the protrusion nor the leaf spring movement limiter is provided.

[0037] (Second embodiment) A fuse connection terminal 2 according to a second embodiment will now be described. The overall configuration of this fuse connection terminal 2 is substantially the same as that of the aforementioned fuse connection terminal 1, except for the shape of the leaf spring used in the terminal portion 50 used here, which is different from the aforementioned leaf springs 12A and 12B. Other than this, there is no difference from the aforementioned fuse connection terminal 1 (terminal portion 10).

[0038] FIG. 5 is a cross-sectional view of the terminal portion 50, taken perpendicular to the z-direction and corresponding to FIG. 2(a). The terminal portion 50 also includes an end face (terminal portion end face 51) on the positive side of the x-direction, an end face opening 51A formed therein, and side faces 53A and 53B. The leaf springs 52A and 52B extend from the openings on the side faces 53A and 53B, respectively. Similarly, protrusions 53A2 and 53B2 and leaf spring movement limiters 55A and 55B are also provided. The cross-sectional view of the terminal portion 50 corresponding to FIG. 2(b) is omitted because it is the same as FIG. 2(b).

[0039] 5, the leaf spring 52A (52B) also has an outer support portion 52A1 (52B1) and a tab terminal abutment portion 52A2 (52B2). However, here, a leaf spring tip bent portion 52A3 (52B3) bent toward the central axis X is provided on the leaf spring 52A (52B) on the negative side of the x-direction and toward the tip of the outer support portion 52A1 (52B1). As shown in FIG. 5, when no force is applied to the leaf spring 52A (52B), the tip of the leaf spring tip bent portion 52A3 (52B3) is spaced from the leaf spring tip bent portion opposing portion 52A4 (52B4), which is the surface of the leaf spring 52A (52B) on the positive (negative) side in the y-direction.

[0040] Fig. 6 is a cross-sectional view corresponding to Fig. 3, showing the state when the tab terminal 200 is attached to the terminal portion 50. In this case, as in Fig. 3, when the tab terminal 200 is inserted, the outer support portion 52A1 (52B1) abuts against the side surface 53A (53B) in the region D, thereby suppressing deformation of the leaf spring 52A (52B), particularly deformation that causes the leaf spring 52A (52B) to tilt significantly. Furthermore, the elastic force of the compressed leaf spring 52A (52B) allows the tab terminal 200 to be stably clamped between the tab terminal abutment portions 52A2, 52B2.

[0041] FIG. 7 is a cross-sectional view corresponding to FIG. 4, showing the state when the tab terminal 200 is inserted into the terminal portion 50 in an inclined state. In this case, as in the case of FIG. 4, no load is applied to the leaf spring 52B, and a large load is applied to the leaf spring 52A. As a result, the leaf spring 52A is compressed, and the degree of this compression is limited by the contact of the outer support portion 52A1 with the side surface 53A in region E. Furthermore, in this case, as the leaf spring 52A is compressed, the tip of the leaf spring tip bent portion 52A3 contacts the tip bent portion opposing portion 52A4 in region F. Therefore, deformation of the leaf spring 52A in the y direction is also limited by this.

[0042] FIG. 8 is a cross-sectional view showing the state when a thick tab terminal 200 is inserted into this terminal portion 50. In this case, the leaf spring 52B also deforms in the same manner as the leaf spring 52A in FIG. 7. In this case, the provision of the leaf spring tip bends 52A3 and 52B3 in both leaf springs 52A and 52B limits the deformation, thereby improving the durability of this terminal portion 50. Alternatively, since the leaf springs 52A and 52B are less compressed in the y direction than in the state shown in FIG. 8, a thicker tab terminal 200 cannot be attached than in the state shown in FIG. 8. This prevents the incorrect attachment of a tab terminal. Alternatively, it prevents the tab terminal from being attached with a foreign object sandwiched between them. This results in particularly high durability of this fuse connection terminal.

[0043] Furthermore, when the tip of the leaf spring tip bent portion 52A3 (52B3) abuts against the tip bent portion opposing portion 52A4 (52A4) as shown in FIG. 8, a large force is required to further compress the leaf spring 52A (53A) in the y direction. Therefore, in the state shown in FIG. 8, the tab terminal 200 receives a large elastic force from the leaf spring 52A (53A), and the tab terminal 200 is fixed more firmly.

[0044] In the above example, the leaf spring has a planar shape as shown in Figures 2 and 5, but as long as the tab terminal contact portion, outer support portion, and tip bent portion of the leaf spring are provided, the shape of the leaf spring other than these portions is arbitrary. In this case, since the leaf spring is formed using the same metal plate as the entire terminal portion, it is preferable to use a shape that allows for easy manufacturing.

[0045] 2 and 5 are symmetrical on the positive and negative sides in the y direction when viewed from the central axis X, but this does not have to be the case. However, when a tab terminal having a symmetrical structure on the positive and negative sides in the y direction is used, it is particularly preferable that the terminal also have a symmetrical structure in this way.

[0046] In the above example, a terminal (fuse connection terminal) that connects one wire and one tab terminal was described, but a similar structure can also be used in a connector that simultaneously connects multiple terminals and multiple wires. However, as mentioned above, this structure is particularly effective when there is a risk that the terminal will be installed in an inclined state, so it is particularly preferable to use it for fuses.

[0047] The present invention has been described above based on an embodiment. This embodiment is merely an example, and it will be understood by those skilled in the art that various modifications are possible in the combination of the respective components, and that such modifications are also within the scope of the present invention.
